To all whom it may concern:

Be it known that I, ALEXANDER W. MARK, a citizen of theUnite'd States, and a resi-. dent of the city of Canton, in the county of Stark and State of Ohio, have invented certainnew and useful Improvements in Tire-Saving Jacks, of which the following is a specification. it

This invention relates to new, and useful improvements in tire-saving jacks.

T e principal-pu a y i 't p s m provide a simple, inexpensive and efficient jack-set for the purpose of relieving the tires-of an automobile or other vehicle from theweightof thebody when the latter is not in use. .A'nother object ofthe inventionis toprovidla toggle-lever operating mechanism which is readily detachable from the jack proper, so that one operating lever they be easily applied to each of four. Jacks, one

for each wheel of an automobile, thereby-reducing; the cost of the set very materially.. Other important and incidental obiectswill be set forthinthe following specification and particularly pointed out the subioined claims.

The preferred form of embodiment of I my invention is illustrated in the accompanying drawings, of which Figure 1 is a sideelevational view of my improved jack, with the toggle-lever a plied thereto in position to raise the lifting bar. Fig. 2 is aside view of the upper portion of, the iack,

showing, the, position of the toggle-lever after. the lifting bar has been raised. ,Fig. 3 is a side view of thejpawllliolding he Iiftingbar its elevatedposit on Fig.

1n a detailed description of the preferred f rm of embodiment of: mv in e tie il the numeral 1' 1 design ates a- Standard mounted upona base 2. The is 7 ndard 1 is .tiihnlargto lifting bar 3 to; the top of which a concaved head 4 is pivoted for a. horizontal turning movement thereon. In order to prevent the lifting bar 3, which is preferably circular in cross section, from turnin within the standard 1, the latter contams a front vertical slot 5 that loosely receives a guide screw 6 secured to the lower end of said lifting bar. (See Fig. 6.)

Fixedly secured to theupper end of the lifting bar 3ja; short distance below its head 4, is a collar 7 which consists of a metallic ,bandthat does not completely surround the bar 3vbut whose ends extend outwardly from a place in. its periphery in the between these ears 8 8 lis a. bolt 9' which is. tightlyfsecured thereto by means of a nut 1 ).r The bolt 9 loosely passes through the upper end of a downwardly pointed patwl'illso constructed and positioned bejarred loose as in many otherv jacks. To

permit the bar'3 to -.be lowered, the nose portion 12 of said pawl must be withdrawn from. engagement. with the top edge of the standard 1, whereupon said bar will drop down into the standard. a V

For the purpose of easily raising and low ering'the bar 3 after its head 4 has been placedunder a load, the following described lever mechanis'm. is provided. -.Referri ngto :Fig'sJL 2 andT. the-numerals-13 13 n'ate aipair of similar fulcrum arms, Each arm..13 has near its inner end a downwardly extending boss endof each a notch ,15 is provided.
